As indicated in the severalfigures of the drawingg-amy improved anchor has the form of a lat-' upper corners ofthe "window sashg-with the cable omitted erallyextended plate member generally designat 'l ed"9 W1'IiCh"lS suitably fixed to the upper edgeof Like reference characters L designates? corresponding parts in the several figures of the drawing, wherein I generally denotes a window structure of the double-hung, vertically sliding sash type, said window structure being equipped with sash balancing means of the type disclosed in my prior application hereinbefore referred to. Only a portion of the window structure is illustrated in Figure 1, but said portion includes one sash, designated 2, which is vertically slidthe sash near the corner-thereof; as by means of-a screw I 0, orother appropriate fastening. The laterally extended marginal edges of the plate 9 are disposed parallel to each other for the major portion of their length, and are prefextreme end of the plate inwardly for a distance at least equal to the width of the cable 6. This slot I2 is disposed substantially parallel to the laterally extended marginal edges of the plate 9 and is located intermediate said edges, but preferably somewhat closer to one edge than the other. It will be further noted from the drawing that at least those portions of the flanged marginal edges H, H of the plate 9 which are in transverse registry with the slot 12 are smoothly curved or rounded and are wholly devoid of sharp corners, as indicated at [3, I4, and one of the edges, namely, the edge 13, is transversely offset somewhat beyond the flange H at the corresponding side of the plate 9;

In attaching the cable 6 to the sash 2 by means of the anchor member or plate 9, the

cable is extended transversely across the bottom of the plate at the slotted end thereof from one extreme marginal edge to the other. The extreme free end of the cable is then looped about the forward edge of the plate and then is extended downwardly through the slot l2 and thence between the bottom face of the plate and the underlying advance portion of the cable, back to the first marginal edge of the plate. Any excess or surplus end of the cable remaining may be bent over so as to lie flat against the upper face of the plate, as indicated at I5. The opposite edges of the slot l2 are preferably inclined in the direction of lead of the cable to prevent cutting of the cable.

By the use of an anchor constructed and arranged as above described, the cable 6 can be quickly attached to the sash 2 or detached therefrom, at will, and when so attached, the greater the tensile strain upon the cable, the greater will be the gripping efiect tending to clamp the extreme free end of the cable between the plate 9 and an advance portion of the cable ahead of the slot l2, with consequent increase in frictional contact and anchoring effect on that portion of the cable which is looped about the forward edge of the plate.

I have found from actual use of anchors constructed in accordance with the present invention that the cables will remain firmly attached to the window sash without any tendency of slippage or accidental detachment, and are capable of sustaining weights up to the maximum tensile limits of the cables.

Instead of employing separate anchor plates of the form illustrated in the drawing, the same results can be obtained by forming the anchor as an integral part of the upper edge of the window sash, particularly where the sash ismade of metal. In any case, it is advisable to eliminate all sharp corners wherever the cable makes an abrupt turn or bend about the anchor, in order to minimize chafing or accidential cutting of the cable.

Other uses of my improved anchor will readily suggest themselves to those skilled in the art, and it is to be understood that my invention is 4 the spirit thereof as defined by the appended claims.

I claim:

1. An anchor for flat members such as cables, tapes, bands and the like, comprising a laterally extended anchor plate member having a laterally extended slot in one end thereof extending to the extreme lateral end of the plate member so as to be open at one lateral end of the plate member, said slot being of a length at least equal to the width of the flat member, said slot being located between and disposed substantially parallel to the laterally extended marginal edges of the plate member, the slotted end of said plate member being arranged to receive one end of the flat member beneath the same, with the fiat member extended from one lateral marginal edge to the other and then reversely folded about the latter edge and across the upper face of said plate member to said slot, then downwardly through the slot and across the lower face of said plate member between the plate member and the first-mentioned underlying portion of said fiat member, to the first-mentioned lateral marginal edge of the plate member.

2. An anchor as defined in claim 1, wherein the opposite edges of the slot are inclined in the direction of the lead of the flat member, said edges of the slot being in parallel spaced rela- ;tion to each other, the space therebetween being only slightly greater than the thickness of the fiat member.

3. An anchor as defined in claim 1, wherein the laterallyv extended marginal edges of the plate member are extended outwardly from one face of the plate member to form marginal flanges.

4. An anchor for flat members such as cables,

tapes, bands and the like, comprising a laterally not limited in its application to the anchorage While the specific extended anchor plate member having a laterally extended slot in one end thereof, said slot beinglocated between and disposed substantially parallel to the laterally extended marginal edges of the plate member, the flat member-engaging portion of one of said laterally extended marginal edges of the plate member being transversely offset beyond the remainder of said edge, the slotted end of said plate member being arranged to receive one end of the fiat member beneath the same, with the flat member extended from one lateral marginal edge to the other and then reversely folded about the latter edge and across the upper face of said plate member to said slot, then downwardly through the slot and across the lower face of said plate member between the plate member and the first-mentioned underlying portion of said fiat member, to the first-mentioned lateral marginal edge of the plate member.
